| 摘 要： | 本研究利用平行因子分析法(PARAFAC)完成了甲苯、苯和甲醇三组分体系的遥感傅里叶变换红外光谱(FTIR)谱图的同时定性定量分析.在有丙酮干扰情况下,定量分析的误差分别在6.61、18.76、16.00以下.将PARAFAC的输出结果作为偏最小二乘法(PLSDA)模型输入,实现了定性分析的自动完成.对主动式下数据定性分析的识别率和拒绝率均为100%,对被动式下数据的拒绝率为90%,识别率为85%.分析结果表明,PARAFAC可以同时进行定性定量分析,避免了干扰物存在的影响,可以满足遥感FTIR对多组分体系的实时、在线监测的需要.

| Abstract: | Remote sensing Fourier Transform Infrared Spectrometry(FTIR) can be used for the analysis of complex system with the aid of multivariate calibration methods,however,the prediction results were deteriorated due to the difference between prediction set and calibration set.Three-component system containing toluene,benzene and methanol were interpreted in qualitative and quantitative way simultaneously with the method of PARAFAC(parallel factor analysis) in this paper.With the interference of acetone,RSDs of th... |
